Zetec turbo wastgate problems
 

Iv got a problem with my wastgate its a cheepo type I think I dident buy it new no names stamped into it the manifold is SPA and then I go on to the SPA ate they sell a wastgate that looks just like mine so probs is a SPA gate as well the prob iv got is the actual vale in the gate actually seals onto the manifold itself but neither are totally flat it's ment to have a 7 psi spring in it but to get the valve to seal on the manifold property I have to tighten the spring to the extent of it boosting at 11psi to much for my engine . So what I'm wondering is do some wastgates that seal within there selfies rather than relying on the seal between the valve and manifold?

Speak english, or post some pictures of what you are trying to describe.

And if something isnt flat, make it flat.
